3 Claims. (01. i99-s0) This invention relates to improvements inapparatus for casting quads or spacers, such quads or spacers for use asparts'of the novel form of printing plate such as broadly disclosed inmy co-pending application, Serial No. 747,158 filed October 6, 1934, ofwhich the present application is a division.

In carrying out my invention, I utilize a standard or commercial form oftype-casting machine,

but provide certain simple modifications in construction thereof so asto produce a quad or spacer having a cylindrical aperture or holeextending through the full length thereof.

I The invention maybest be understood by ref- 'erence to theaccompanying drawing, in which Fig. 1 is a perspective View of atype-casting machine of a well known commercial form, in

- which certain modifications have been made so as to adapt it to theproduction of the novel form of quads above referred'to.

Fig. 2 isa perspective view of a single quad which is produced in anovel method herein disclosed.

Fig. 3 is a fragmentary side view of the modified lever mechanismemployed in the machine shown in Fig. 1.

Fig. 4 is a perspective view of a standard form of matrix carrierutilized in the type-casting machine shown in Fig. 1, but having appliedthereto a cylindrical matrix for forming the elongated holes in thequads shown in Fig. 2.

Fig. 5 is a detailed transverse sectional view showing the variousportions of the type mold and matrix utilized in my improvedtype-casting machine.

Referring now to the embodiment of my invention illustrated in thedrawing, the product to be manufactured thereby is shown in Fig. 2 whichconsists of a single block forming a square quad of standard length.Said block is provided with a hole 2| which is preferably of reduceddiameter near one end thereof so as to leave an undercut shoulderindicated at 2W. These blocks or quads are specially designed forutilization in the novel form of printing base fully disclosed in myparent application above referred to. For the present application itwill be sufilcient to. state that the holes 2| are designed toaccommodate plate hooks of the well known form which are detachablyconnectible in the holes 2! and engage the shoulders Zl therein so as tosecure the margins of printing plates to the top of the base formed by aplurality of such quads or blocks 20;

Referring now to the preferred method of producing the quads 20 on atype-casting machineso as to form the holes 2! extending lengthwisetherethrough, I have illustrated portions of a standard Thompsontype-casting machine which has been modified so as to produce my novel 5form of quad. The principal parts of said typecasting machineillustrated herein include a matrix carrier 40, matrix carrier fork 4|,carrier lever 42 and carrier cam 43.

The matrix carrier forms the outer end of a 10 mold shown in section inFig. 5 in which one side mold blade M is movable downwardly, theopposite mold blade $5 is movable horizontally, and the end of the moldopposite the matrix carrier 68 is closed by a plate 46. 15

When employed for making standard type, the matrix carrier usually hasremovably mounted thereon a matrix (not shown herein) carrying theimpression which forms the character, letter or other figure of eachtype. The matrix carrier 20 is given limited horizontal movementsufficient to withdraw the matrix from the type after it has been cast.Simultaneously the vertical mold blade at is withdrawn downwardly, andthe opposite mold blade 45 is then moved toward the 25 left as seen inFig. 5 so as to discharge the finished type onto a suitable rack (notshown). The mold blades 44 and 45 are then returned to their normalposition, and the matrix carrier 40 closes the end of the mold ready forforming the next 30 type in the same manner.

It will be understood that in the operation of the standard type-castingmachine as above described, the amount of movement required for thematrix is relatively small, since it is only 35 necessary to givehorizontal clearance for the height of the character impression at theend of the mold. This limited movement is provided by a matrix carrierlever usually mounted on a cam lever shaft 50 mounted in pillow blocks40 5!, 5|. The length of the matrix carrier lever and the throw of thematrix carrier cam in such standard machine is relatively small, so asto produce a travel of the matrix carrier which usually does not exceedof an inch for form- 45 ing the largest forms of type.

In order to produce my novel form of quad 20, with an elongated holeextending the full depth thereof, I have modified the standard form oftype-casting machine in the following manner: 50

A matrix plate 55 is mounted on the matrix carrier 40 in the usualmanner, but said matrix plate carries a projecting cylindrical core 56adapted to extend the full length of the mold formed by the matrixcarrier 40, the mold blades 55 .56 from the mold, I provide an auxiliaryshaft V 60 mounted on supports 6|, 6| secured to the outer face of thepillow blocks of the typecasting machine, so that the axis of the shaft60 is disposed a point substantially outside of and below the axis ofthe cam lever shaft 50 on which the shorter lever, usually employed withstandard type matrix, is pivoted, as previously de-. scribed. The matrixcarrier lever 42 is, therefore, substantially longer than the usualcarrier lever for which it is substituted. Similarly, the

throw of the matrix carrier cam 43 is greater than that of the. standardcam which it replaces, ,so as toprovide the necessary increase in travelof the matrix carrier and core 56.

From the above description, it will now be seen that the individualquads may be produced in large quantities in astandard type-castingmachine modified as described, the only changes necessary being .theprovision of increased travel of the matrix carrier and the substitutionof core 56 for the usual matrix plate.

It will be observed, however, that the finished quads 20, 2!] areutilized for forming the base in a position that is reversed or invertedwith respect to the usual printing arrangement of reg- V ular type, whenthelatterare formed in the same machine.

In other'words, when ordinary type are inserted in the base plate, thematrix ends of such type are facing upwardly in the base whereas thecorrespondingmatrix ends of the quadsare disposed at the bottom of saidbase. Although I have illustrated and described one particularembodiment of my invention, it will be understood that I do. not wish tobe limited to the exact construction shown anddescribed, but thatvarious changes and modifications may be made without departing from thespirit and 6 scope of my invention as defined in the appended claims. V

I claim: 7 r i 1. In combination with a type-casting machine having anelongated mold and a matrix carrier 10 movable longitudinally relativethereto, an attachment for said matrix carrier comprising a matrix plateadapted to close one end of said mold andhaving a core of the samelengthas said mold, and means for imparting longitudinal reciprocable movementof said matrix plate and core relative to said mold for substantiallythe full length of'the latter.

2. In combination with a type-casting-machlne having an elongated moldprovided with movable side walls, and a matrix carrier movablelongitudinally. relative to said mold, an attachment for said matrixplate adapted to closeoneend of said'mold and carrier comprising amatrix having a cylindrical core of the same length of said moldandaxially movable relative thereto, and means for imparting longitudinalreciprocable movement of said matrix plate and core into and'out of saidmold in timed relation with the movement of saidside walls.

3. In combination with a type-casting machine having anelongated moldand a matrix carrier movable longitudinally relative thereto,anlattachment for said matrix carrier comprising a matrix plate adaptedto close one end of said V mold and having a'cylindrical tapered core ofthe same length as said mold, said core having 7 an oifset shoulderintermediate its ends, and 7 means for imparting longitudinalreciprocable' movement of said matrix plate and core for sub 40stantially the full length of said mold.
